This custom continued until 283 AC, when the Targaryen dynasty was ended at the conclusion of Robert's Rebellion. King Aerys II Targaryen and his eldest son, Prince Rhaegar Targaryen,[2] were slain, as were Rhaegar's children, Rhaenys and Aegon.[3][4] Aerys's sister-wife, Queen Rhaella Targaryen, had fled to Dragonstone with her younger son, Viserys, shortly before the end of the war, where she spent nine months until her own death in childbirth during a fierce storm.[5] During this time, Rhaella crowned her son Viserys king,[6] and following the birth of his sister, Daenerys, Viserys named her Princess of Dragonstone.[5]

The Targaryen children were forced to flee before the assault on Dragonstone, however, and the castle was captured by Stannis Baratheon, the younger brother of the new king, Robert I Baratheon.[7] Robert gave Stannis Dragonstone as his seat, making Stannis the first Lord of Dragonstone in nearly three hundred years.

Aegon Targaryen, Aerion's son. Aegon became known as King Aegon I Targaryen, Aegon the Dragon, and Aegon the Conquerer.[1] He was the last Lord of Dragonstone from House Targaryen, and the first Lord of the Seven Kingdoms.
